In pictures: 10 new towns and garden cities through history

Founded: 1920
Welwyn in Hertfordshire is the second garden city to be founded in England.
The town is laid out along tree-lined boulevards, with every road having a
wide grass verge. The spine of the town is Parkway, a central scenic parkway
which is almost a mile long. The original planners had intended all the
residents would shop in one store, but due to local resentment and
commercial pressures this idea was abandoned.
